meseen Elpeclflcstion of Letters Patent.

rstenteonpr. is, leis To all whom it may, concern Be it known that 1, JOHN H. Hons, a citizen of the United States, residing at the city of Paterson, Passeic county, Etste of New Jersey, have invented certain new and useful improvements in Nut-Locks; and. l

xlocleclere the following to he a full, clear,

and exact clescription of the invention, such es will enable others skilleol in the art to which it alppertains to make and, use the same. v

This invention has reference to nut locks, which are in the general form of segments of a. helical coil of suitable metal, and the object of the invention is to increase the resistance afiorcled by the nut locks against the clamping elements.

In the accompanying \irevving Figure 1 is a plan View of the nut locks-Fig. 2 an edge elevation of the not lock looking to ward. the extremities of the segmcnt Fign 3 on edge elevation of the nut look when "view-c6 from. a point at right angles from that of 2, ancl at is an edge QlBVlL" tion of the not lock viewed from a point directly opposite to that of Fig. 3.

Similar numerals of reference denote like ports in the several figures of the drawing.

in the present invention portions of the helical. scqment of the nut lock are bent or displaced transversely by slightly twisting certain portions of the entire body of the helical segment about an axis which extends along the length of the spiral curve so that such portions are displaced out of the normal curvature of the helical segment,

The new spiral. curves of the tvvisteol pox tions have a pitch diilerent' from that of the original helieel segment, and, of course, the surfaces of the twisted portions are all at an angle to the surfaces of the original helical segment. Preferably this twist is formed in two oppositely disposed portions of the heli-v col segment and in such case the twisting is prefereblyefi'ected in reverse directions, but this invention is not limited. to this detail.

Referring to the accompanying (l-rowing, the numeral 1' is used to designate the nut lock generally speaking, 2 designates the inner edge of the helical segment, 3 closi-gnates the outer edge thereof, and 4: des ignetes the portions that are twisted.

What is claimed is 2- i 1; A nut-lock, consisting in general form of a segment of av helix, having certain portions tirvisteclv about an eXis extending lengthwise of the helical segment.

2. A nut-lock of helical form, each end of the nut-lock being; twisted. or tilted, in the direction, of its Width, out of line With the normal surface of the helix. 7 i

3. A nut-loclnof helical form, each enol losing tvvisteni transversely, in the uirection of its width, out of line with the normal helilal surfaceonel having a pitch difierent from that of the adjacent body portion.-

4. A nut-lock of elicul form, having that portion of the hotly scent each end twisted transversely, in the (lirection of its. Width, out of line with the normal surface of the helix, the twist in one end being in a direc tion. the reverse oi that in the other.

5. A nut-lock helical form, having a portion of the local}! t isted. or tilted, in the direction of its \i-idth, out of line with the normal surface of the helix.

In testimony whereof I siiizr my signature witnesses.
